A word of warning when trying to move the pump out of the way with the
hoses connected. I did this on my Coupe quattro to change the
thermostat (actually, talking about chintzy, I was only replacing the
o-ring), which is about as crowded as a 3B is. I undid it at the
bracket and moved the PS pump out of the way, and in doing so I
inadvertently loosened one of the banjo bolts and it leaked at a
fitting by the firewall. I tightened that up only to blow the crusty,
rusty hose while driving it and had to tow it home. I ended up
replacing the hydraulic hose with a junkyard one.
Just keep in mind if your hoses are all old and rusty, that they may
not want to be flexed very much. It might be better to unbolt the
hoses at the pump or something rather than disturbing the hoses, if
you are comfortable with leaving the hoses like that instead of
replacing them. Another approach might be to wrestle with everything
and replace anything that breaks while you are not on the road.
I will say that getting the PS pump out of the way seems to be the
best approach for thermostat R&R, perhaps MFTS too.
